Copyright Ownership to Historical Contents in the Open
Get PDFIn this paper we discuss the various steps followed while
creating an open access repository of historical material available at the
Indian Institute of Astrophysics using DSpace. While uploading these
materials we have come across various copyright issues, which are not
clearly addressed by the Indian copyright act of 1957. Moreover the
Indian copyright act pertaining to digital contents is still not complete to
include the historical contents. Some of these issues are understood in
the context of copyright laws prevalent in other countries. Archival
collections of IIA Open Access Repository are classified under the
communities; (1) Archival collections, (2) Research papers in journals
where IIA is the publisher (3) News paper clippings, (4) Photographs.
This paper mainly elaborates on the procedure followed according to
the ownership of the materials available with us and also those, which
are transferred to us by the relatives of the original authors. The
procedures also include the efforts made to trace the possible owners of
the contents for copyright clearance. This paper also focuses on the
basic principle, that holding an archival material does not automatically
give the library copyright ownership. It creates an awareness among
library personnel regarding the legal aspects of archiving historical
contents like old newspaper cuttings, photographs, letters and handwritten
manuscripts
vascoda.de and the system of the German virtual subject libraries
Get PDFvascoda.de is a German internet portal for everyone looking
for scientific and scholarly information. It offers user-friendly access to
reliable information and full texts from an extremely wide range of
different subject areas. vascoda.de is based on a system of virtual
subject libraries like, for example, econbiz.de, the virtual library for
economics and business studies. These virtual libraries deliver the
content being presented in vascoda.de and they also offer additional
services and content not being part of vascoda.de
Evaluation of Digital Libraries
Get PDFThe paper discusses the need for digital library evaluation. It
provides insight into a framework for digital library evaluation. The
paper also discusses various evaluation techniques in detail. Examples
of major digital library evaluation projects underway world-wide are
also included. The paper presents a detailed case study of digital library
evaluation conducted by the Management Development Institute, India.
Techniques used and the results of the evaluation are also discussed
OILSW: A New System for Ontology Instance Learning
Get PDFThe Semantic Web is expected to extend the current Web by
providing structured content via the addition of annotations. Because of
the large amount of pages in the Web, manual annotation is very time
consuming. Finding an automatic or semiautomatic method to change
the current Web to the Semantic Web is very helpful. In a specific
domain, Web pages are the instances of that domain ontology. So we
need semiautomatic tools to find these instances and fill their attributes.
In this article, we propose a new system named OILSW for instance
learning of an ontology from Web pages of Websites in a common
domain. This system is the first comprehensive system for automatically
populating the ontology for websites. By using this system, any Website
in a certain domain can be automatically annotated
Watermarking based content security and multimedia indexing in digital libraries
Get PDFEncryption, digital signature and digital watermarking are
the key techniques used in content protection and security
applications. Latest technology to prevent the digital content from
piracy and preserve the ownership information is to watermark the
digital content. Watermarking the digital content with origin
information or intended recipient identification secures content from
electronic data theft. In digital libraries enormous collection of data
is available in the form of multimedia (image, video, graphics and
audio) and needs to be abstracted to provide the end users for easy
access to the digital library. The multimedia contents are indexed by
origin, date and time of content creation, key words and titles. In this
paper, watermarking based content protection (authentication) and
digital index creation for multimedia information has been proposed.
In order to support the users for efficient use of available channel
bandwidth, high quality videos and universal supported formats,
digital libraries are supported with real time applications like video
streaming, compression, and transcoding. The compute intensive
operations of the video processing applications make a big challenge
to the existing systems, so hardware solutions for the above
problems are also presented to improve the digital video library
performance
Semantic binding of classical and digital library system
Get PDFThe automation of bibliographic catalog and house-keeping
operations in a library and/or the introduction of digital library system
have seldom delivered context-specific or personalized information for
the end user. The existing cataloging and classification rules do not
provide intelligent mechanism to store and retrieve ever-expanding
information resources. Adopting semantic technology with ontology as
the formalism to represent all resources can provide a better system for
information storage and retrieval. This paper presents a resource
ontology developed using any cataloging rule to provide semantic
description of the resources (both printed and digital) of a library and
the technical solution architecture to provide semantic library services
triggered by an ontology management infrastructure and software
agents. Separate ontologies to manage user community, classification
scheme and subject categorization of resources enhance the semantics
of user management and information retrieval
User interface design and development: the role of open source systems
Get PDFOpen Source movement has tremendously influenced
Information industry, in particular the Digital Library
Environment where the Information Systems and services are
inevitable. This has helped the Library and Information
Centers in developing User Interface to render web based
services to the patrons. Wherever the network infrastructure
and the target users are in place, the design and development
of IR user interface using Open Source system for a specific
application is very much possible. This paper highlights the
role of Open Source Systems in detail and explains a prototype
IR User Interface which was developed in-house at Indira
Gandhi Centre for Atomic Research, Kalpakkam
Open Access: What Scientists Think?
Get PDFThe Internet has changed how we conduct and share research,
primarily by increasing the global reach of scholarly communication.
Today the world of information is divided between two views on costs
and business. One group believes that content should be freely
accessible for the development of further knowledge. The other group
believes that content should be maintained by market value for quality
products and incentives to the intellectual content.
Open Access (OA) has come from the growing interest of researchers in
experimenting with innovative mechanisms to disseminate their
research findings. However OA is still far behind what it should be in
the country like India. At least the scientific community is still in a
dilemma to embrace OA. This is what we find in our survey of
researcher's attitude towards OA. There are many reasons ranging from
lack of awareness, myths about OA and biasness towards traditional
publishing model for prestige & recognition.
We approached scientists of different research institutes and universities
around Kolkata with different age groups in different ways. Interesting
results have come out which clearly identified the major hurdles to
adopt OA by scientific community in India
The Concepts of Semantic Heterogeneity and Ontology of
Get PDFvascoda (www.vascoda.de) is today the most important project to
achieving a new innovative infrastructure in the field of scientific
information in Germany. The aim is to integrate high-quality information
from the deep and from the visible web by using search engine technology
(FAST) and new concepts to integrate the data, not only technically, but to
solve the problem of semantic heterogeneity at a high level of quality. In
contrast to the ontology and semantic web approach that of semantic
heterogeneity in the context of the shell model started from the invisible
web, opening itself to the visible, not vice versa, and is putting the reuse of
existing semantic knowledge (thesauri) in the foreground. The
consequences of these differences and the common features of both
approaches are in the focus of the paper
Role of semantic web in the changing context of digital environment
Get PDFThe Semantic Web can aid effective knowledge management
and cost-effective product life cycle automation for faster development
and integration processes. The essential property of the World Wide Web
is its universality. The power of a hypertext link is that "anything can link
to anything." Web technology, therefore, must not discriminate between
the scribbled draft and the polished performance, between commercial
and academic information, or among cultures, languages, media and so
on. Information varies along many axes. Present paper attempts to
highlights the fundamental role of semantics web in post modern
electronic information society
